Ubuntu 14.04 LTS / 15.04 : click vulnerability (USN-2771-1)

Medium Nessus Plugin ID 86415


The remote Ubuntu host is missing a security-related patch.


It was discovered that click did not properly perform input sanitization during click package installation. If a user were tricked into installing a crafted click package, a remote attacker could exploit this to escalate privileges by tricking click into installing lenient security policy for the installed application.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected python3-click package.
